. 1Be it known that I. WILLIMI THos. Woon, a citizen of the United States. residing at Xashville, in the county of Davidson and State of Tennessee. have invented a new and use ful Tire, ot' which the following is a speci- It, is of course' well known that with the ordinary tire, pressure brought against the outer wall causes the separating and doubling the side Walls, .and permitting 'their ready collapse. i* t One of the. principal objects in the present invention is to provide a cushion tire, having novel means to supsaid wall moves inwardly, the resisting power of, the side wallsnioreover, lbeing at all times maintained. Moreover, Vit is a well known'fact that when the tread surface of a tire becomes cut, the sand and dirt forced int'o the cuts 'will often collect and work laterally along "Anothe'r and important object is to provide a tire that will permit the free escape of matter that may collect in said cuts` thereby avoiding this Very objectionable feature. A

The preierredform of construction is illustrated in Figure l a'longi-tudinal .sectional View. through av portion of a tire, constructed in accordance with the line 3 -.-3 of Fig. 2., showing the under side of the tread of the supporting posts. l

'Similar reference numerals designate corresponding parts in all the figures of the drawings.

embodiment may be comparatively thin, an outer Wall an inner wall comprising sections 7, the said sections having outstanding ribs S arranged to interlock with the lagainstthe inner faces of the inner wall sections 7 to Within the casing are arranged a plut-alimy of indopendent yielding supporting posts 13, their out-er ends l)eing`.connected to the outer wall 6 preferably by vulcanizat-ion so thatthe parts are in effect integrally joined together. The' inner ends of these posts are alternately connected/to the opposite sides and inner portions of the casing. as shown at 14. Each post furthermore has an intermediate offset web l5, joined to one of the sido Walls, said webs being alternately connected to theopposite side walls, as will bc evident. by reference vto Fig. 2. The portions of each post on opposite sides of its web .lo are bowed in thelsame direction, as shown at 1 6.

The operation ot' the supports may be. briefly described as follows. When pressure is brought against the outer wall of the casing, the posts at first will be compressed. but as this pressure becomes greater, the said posts will bondl` because of their bowed formation, on opposite sides ofthe webs. Atthe sante time this bowing action will tend to force the webs inwardly, and thus prevent the outward collapse ofthe side Walls. The result is a tire that is very efficient-ly supported, and yet is yielding so as to absorb the shocks and jarsincident to its use. In orderto avoid the cracking of the posts due to crystallization of the rubber or tho like, the edges of said posts and webs that are free, are preferably covered with strips of fabric 17.

Extending over the outer side of the casing is a tread element 18. This tread element is provided with a centrallongitudinally disposed rib 19 and triangular projections 2() located on opposite sides of the rib, said projectionsv being spaced from each other and from the rib. The rib and projections 20 are joined integrally to the outer Wall of the casing, and as a result passages 2l are formed' between the tread element and casing, saidpassages having contracted open mouths 2210- cated at the edges of the tread element. Wit-h this construction it the tread element is cut, the sand and dirt that is forced into such cut will pass into one of the passages and find a free passage through the outlet mouth 22 of such pocket. Moreover, inasmuch as the pressure upon the tire forces any such matter outwardly, itwill be evident that the material Wiil find a ready exit. As a lresult, it- Will be evident that a comparatively simple tire is provided, which is selfsustaining. is sufficiently yielding, is durable, and can be manufactured at comparatively small cost.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those."skilledx4 Having thus fully `described my invention, what 110 claim as new, and desire to secure by Letters Patent, is:-`

l. A tire comprising a tubular casing, and a plurality of separate yielding supports located one behind the other within and connecting the inner and outer portions of the casing. said supports having separate lateral webs con-, nected to the sides of the casing.

2. A tii'e comprising a 4tubular casing, and a plurality of independent yielding supports located one behind the other Within and connecting the inner and 'outer portions of the casing, said supports having yielding webs that are alternately connected to the opposite sides of the casing.

3. A tire comprising a tubular casing, and a plurality of separate oppositely bowed laterally yielding supports located one behind 'the other within and connecting the inner and' outer portions of the casing. A

4. A tire comprising a tubular casing, and aplurality of separate laterally yielding independent spaced supports located within and connecting the inner and outer portions of the casing, said supports being alternately bowed in opposite directions. I

A- tire comprising a tubular casing, and a plurality of separate laterally yielding supports located within and connecting the inner and outer portions of the casing, certain of said supports being bowed inone direction, others in au opposite direction transversely of the tire, each support having an intermediate web connected vto the side of the easing away from which it is bowed.

6. A tire comprising av tubular casing, andv a plurality of oppositely bowed laterally -yielding supports located the portions on the opposite sides of the web bowed in the same direction.

8. A tire comprising a casing, and a tread element lextending ov'er the outer portion ot the casing and having portions free from said casing, forming a dirt-receiving passage between the casing and tread elements, said passage having an open mouth. v

S). A tire comprising a casing, and a -tread element eX tending over the outer portion of the casing, said tread element having portions secured to the casing, and portions free therefrom forming afdirt-receiving passage, the said passage tapering to one side and having a restricted open mouth at one edge of the tread element.

10. A tire comprising a casing, and a tread element eX- tending over the outer portion Fof the casing, said tread aow/ia extends over Vthekouter side ot-he casing, a longitudinal.

rib connecting the intermediate portion of the tread element, and the casing, andfa plurality of spaced Substanz` tially triangular portions connecting the marginsofthe tread fo thepcasing on opposite. sides of the rib, thereby.`

forming passages between the tread elem'ent .and'casing. said passages havingouter open mouths'along the ed s of the tread.

` 13. A tire comprising a tubular casing, a plurality of"` yielding supports'located within and connecting the' inner and outer portions of the casing, said supports having lateral webs connected to'the sides of the casing, yand fabric covering the sides of the support thatv are free from saidcaSing.

14. A tire comprising oppositely bowed laterally yieldingvsupportrs located within and Ahaving their ends secured to the inner and outer po'r tions of the casing, and fabric covering the opposite sidesv of the supports between the secured ends. v

15. The'combination with a rim having seats, of a tire comprising a tubular casing having an inner sectional wall, thesections ofs uch wall having outstanding ribs that interlock inthe seats of'the rim, separate. supports engaglng the outer tire wall and respectively secured to thc sections .of the inner wally said supports permitting the spreading of said sections, a holding strip located between the sections of the inner wall, and fastener means engaging the strip. I

1 6. The combination with arim having' seats; o a tire comprising a ltubular casing having an i'nner sectional wall,` the sections of said wall having outstanding ribs' that.

engage in the seats of the rim, separate supports secured WILLIAM 'r1-ies, woon. s
